The present disclosure relates to a curable composition comprising: (A) a polyolefin; (B) a fumed alumina; (C) a silane compound; (D) a UV stabilizer; and, optionally, (E) a crosslinking agent, where the curable composition demonstrates improved electrical properties. The present disclosure further relates to a crosslinked polymer composition that is the reaction product of the curable composition, where improved electrical properties are demonstrated as well.

Polyolefin compositions having improved electrical properties

The present disclosure relates to a curable composition comprising: (A) a polyolefin; (B) siliceous earth; (C) a crosslinking agent; (D) a crosslinking co-agent; and, optionally, (E) an additive component, where the curable composition demonstrates improved electrical properties. The present disclosure further relates to a crosslinked polymer composition that is the reaction product of the curable composition, where improved electrical properties are demonstrated as well.

Polyolefin compositions having improved volume resistivity

The present disclosure provides a crosslinked polymeric composition. The crosslinked polymeric composition contains (A) a silane functionalized ethylene-based polymer and (B) inorganic hollow microspheres having (i) a Dparticle size from 10 μm to 100 μm, (ii) a crush strength from 17 MPa to 140 MPa, and (iii) a density from 0.10 g/cc to 0.40 g/cc. The crosslinked polymeric composition has a tensile strength from 11 MPa to 40 MPa and a tensile elongation from 12% to 100%.

Crosslinked polymeric composition and coated conductor

A filling composition comprises (A) a mineral oil having a kinematic viscosity from 80 cSt to 100 cSt at 40&#xb0; C.; (B) a styrene-ethylene/propylene diblock copolymer; and (C1) a propylene/ethylene copolymer having a weight average molecular weight (M) from 5,000 to 200,000 or (C2) an ethylene/propylene copolymer having a weight average molecular weight (M) from 5,000 to 200,000. The filling composition is used as a filling composition in a buffer tube.

Filling composition for optical fiber cables

A polyolefin composition is foamed by a process in which a nucleator is used, and the nucleator comprises 80% or more of unagglomerated fluororesin particles and/or agglomerates of fluororesin particles in which both the unagglomerated particles and the agglomerates are less than 1 &#x3bc;m in size.

Process for foaming polyolefin compositions using a fluororesin as a nucleating agent

A process of foaming a polyolefin, e.g., polyethylene, composition using as a nucleator a combination of (A) azodicarbonamide, and (B) a mixture of (1) a first component consisting of at least one of citric acid and an alkali metal citrate, and (2) a second component consisting of at least one of an alkali metal citrate, a di-alkali metal hydrogen citrate, an alkali metal dihydrogen citrate and an alkali metal bicarbonate, with the proviso that the mixture is not solely composed of alkali metal citrate.
